ATTACHMENT T0 BILN'ZDE'ES.

Application filed July 1, 1919, Serial No. 307,960. Renewed March 23, 1823.

To (ZZZ whom it may concern e it known that I, THOMAS DURRANT, of the town of Harptree, in the Province of Saskatchewan, Canada, have. invented certain new and useful Improvements in Attachments to Binders, of which the following is the specification.

The invention relates to improvements in attachments to binders and the principal object of the invention is to provide a device mounted on the binder deck and associated with the packers and designed to positively effect the passing to the packers of the short grain passing over the rear side of the deck.

A further object of the invention is to construct the device in a simple and durable manner and so that it can be readily applied to the present forms of binders without materially changing the structure thereof.

A still further object of the invention is to Construct the attachment so that it can be adjusted when required.

With the above objects in view the invention consists essentially in an. endless belt mounted on the upper face of the deck towards the rear side and disposed at an angle in respect to the deck and suitably driven from the binder mechanism, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claim, reference being had to the accompanying drawing in which Fig. 1 represents a plan view of the rear part of a binder deck showing my invention applied thereon. a

Fig. 2 represents a side view of the parts appearing in Fig. 1.

Fig. 3 represents an enlarged detailed sectional view through the deck at X'-X' Fig. 1.

In the drawing like characters of reference indicate corresponding parts in the several figures.

1 represents the ordinary inclined elevator of a binder which is designed to deliver the cut grain on to the deck 2. 3 represents the customary packers associated with the deck and i represents the usual rear driving chain which is driven in the ordinary way from the bull wheel of the binder.

The above parts are of ordinary construction and for this reason I have not considered it necessary to detail them or further describethei'r construction and operation.

In the ordinary binder there is considerable of the crop lost, particularly where the grain is short, this owing to the fact that with short grain a percentage of it is knocked to the back of the table canvas and is elevated at the back of the elevator 1 and, falling on the rear part of the deck, slides down clear of the packers and is lost on the ground. It is this grain that I purpose saving by using my attachment.

The attachment comprises top and bottom spaced plates 6 and 7 of a triangular shape as best shown in Fig. 1, between which I locate rollers 8, 9 and 10 mounted on carrying' spindles 11, 12 and 13. The rollers carry an endless belt 14: fitted with cross slats 15 and the spindle 11 passes through the deck and is fitted with a worm wheel 16, this spindle acting as a driving spindle for the belt and also as a pivot spindle for the attachment which can be swung in respect to the deck and fastened in adjusted position by fastening bolts 17 designed to enter adjusting openings 18 provided in the deck face.

The attachment is arranged so that the side 19 of the belt, that is that part of the belt between the rollers 8 and 9, will catch the short grain delivered from the rear side of the elevator 1 and pass it over the deck towards the packers instead of allowii'ig it to escape over the deck behind the packers as at present occurs.

The worm wheel 16 is driven by a worm 20 mounted on a driving shaft 21 suitably suspended from the underside of the deck and the driving shaft is fitted with a sprocket 22 designed to be driven by the chain 4. -lVhen the device is in actual operation the direction of rotation of the belt is as indicated by the arrow in Fig. 1 and in accordance with the explanation above given it will be obvious that the device will effect a great saving of the grain as it will positively pass all the grain delivered on to the back side of the deck over to the packers so that the said grain will be ultimately bound in the sheaves.

I wish it here to be understood that I do not desire to be limited to the details shown as obviously these could be readily changed without departing from the spirit of the invention which resides principally in the pro-' vision, of an angularly disposed delivering -belt mounted on the rear side of the deck and arranged and operated to catch thev short grain and deliver it to the packers.

timin of the pivot shaft therethrough, stud shafts extending between said plates at the remainingcorners thereof rollers mounted on said stud shafts and on said pivot shaft, an end-- i less belt trained over said rollers, and releasable fastening means insertable through apertures in said binder deckand engage able with the conveyor frame to hold the latter in any adjusted position to Which it may besWung on the pivot shaftv Signed at Harptree, this 22nd day of April, 1919. i
